I'm the owner of toyota yaris from 2013 and I want to know if exist any procedure to add a new remote key to the car. I tried this procedure but the car don't enter in programming mode.

Instructions:

1.With the driver side door unlocked and open slide the key in and out of the ignition twice without turning it. (Should be done within 5 seconds)*2.Close the driver side door and then reopen it, and then close and reopen it again.*3.Put your key in the ignition again and remove it.*4.Close the driver side door and then reopen it, and then close and reopen it again.*5.Put the key in the ignition and then close the door*6.Turn the key to the "On" position without cranking the car and then turn it back to the "Off" position and remove the key.

***If you are only adding an additional key fob to the vehicle turn the key to "On" position only once. If you are "Rewriting All Key Fobs" and clearing the memory, turn the key to "On" position twice and then remove the key

*7.You should have heard the door locks cycle after you removed the key. This means the vehicle is in program mode.**** If the door locks did not cycle you will need to repeat steps 1-6 again, you should completed step 1 within 5 seconds.*8.To program the new Toyota Key fob hold the "Unlock" and "Lock" button on the key fob for two seconds and then release. Then press the "Lock" button for up to three seconds and release. The door should lock and unlock.**If you are programming multiple remotes repeat step 8 for each remote within 40 seconds of step 7. If you wait to long or the other keyless remotes will not program you will need to start from the beginning.**You have now reprogrammed the Toyota Key fob to your vehicle. You may program up to 4 keyless entry remote control fobs per vehicle. If you do not want to pay for the key fob at the dealer you can buy them for a lot less money on Ebay.
